2 Claims.

My invention relates to improvements in the compression links oftractors.

One of the objects of my invention is the provision of a novelcompression link of a tractor, which may be released from its draftingeffort when the tractor is to cross a gully or go up a steep bank, so asto permit the tension links to properly perform their duties, andprevent the implement, that is being drawn by the tractor, from improperinterference with its work.

A further object of my invention is the provision of a novel compressionlink of the kind described, which is simple, cheap, strong, durable, notlikely to get out of order, and which is emcient in its operation.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing, which illustrates the preferred embodimentof my invention,

Fig. 1 is a perspective view of a tractor provided with my improvedcompression link, shown in its operative position.

Fig. 2 is a side view, enlarged of my improved compression link, shownin its operative position.

Fig. 3 is a side view of my improved compression link, shown in therelease position.

Fig. 4 is a top edge view of the compression link, shown locked in itsoperative position.

Similar characters of reference designate similar parts in the difierentviews.

I designates generally a tractor of usual type having the usual twotension links 2.

My improved compression link. comprises a forward upwardly andrearwardiy extending stationary bar 3, and a rear load attaching means,consisting of the following described parts.

Two parallel rear bars 4 are disposed at opposite sides respectively ofthe bar 3 to which they are oscillatively pivoted, adjacent to theirfront ends, on a transverse horizontal axis, comprising a bolt 5, at apoint spaced from the ends of the bar 3.

The bars 4 are provided with releasable locking means comprising a link8 slidable thereon from the locking position, shown in Fig. 2, to arelease position, shown in Fig. 3. In the locking position, the link 6also embraces the adjacent end of the bar 3. A stop block 1 fastened tothe under edges of the rear bars 4 limits the forward movement of thelocking link 6. Said stop block I also serves as a means for limitingthe upward swinging of the bars 4 to their upperoperative position, by

contacting with the under edge of the stationary bar A short bar 8,fastened by two bolts 9 between the bars 4, extends rearwardly back ofsaid bars 4 and has through it a hole ill, by which a draft attachmentmay be made to an implement to be drawn.

The forward bolt 9 serves to limit the rearward movement of the lockinglink 6, to a position, shown in Fig. 3 at the rear of the bar 3, wherethe link permits the bars 4 to lower.

In operation, with the compression link, in its operative position, asshown in Figs. 1, 2 and 4, will perform its functions in the usualmanner. When the tractor is to cross a gulley, or go up a steep hill,the locking link 6 is slid from the locked position, shown in Figs. 1and 2, to the release position, shown in Fig. 3, releasing the bars 4and permitting them to be swung downwardly to the release position,shown in Fig. 3, in which position, the compression link will permit thetension links 2 to properly perform their functions, and prevent thedigging deeply of the drawn implement, not shown, into the soil.

Upon the upward swinging of the bars 4 to the operative position, shownin Figs. 1 and 2, the locking link 8 is slid to the locking position,shown in Fig. 2, in which it will also embrace the bar 3 and hold thebars 4 in the adjusted position.

Many modifications of my invention, within the scope of the appendedclaims, may be made without departing from the spirit of my invention.

What I claim is:

1. In combination with two tension draft links of a tractor, acompression draft link of the kind described mounted on the tractor andhaving a forward upwardly and rearwardiy extending stationary bar, arear load attaching means oscillatively pivoted on a horizontaltransverse axis to said bar' so as to be swung downwardly from an upperload drafting position to a release position, means for releasablylooking to said bar said rear load attaching means in said upper loaddrafting position, and means limiting the upward swinging movement ofsaid rear load attaching means to said upper load drafting position.

2. In combination with two tension draft links of a tractor, acompression draft link of the kind described mounted on the tractor andhaving a forward upwardly and rearwardly extending stationary bar, twoparallel rear bars at opposite sides respectively of said bar andoscillatively pivoted on a horizontal transverse axis to said bar SQ asin be swung downwardly from an upper two bars are in their upper loaddrafting posi-' 5 tion, load attaching means between and fastened tosaid two bars at the rear of said stationary bar, and means limiting theupward swinging 0! said two bars to said upper load drafting position.
